There's a series of Nintendo games called Mario Party, which are made up of a bunch of short minigames played for points. Mario Party 8 is the only one on the Wii so far, and it makes good use of the system's motion controls. One game on MP8 that I don't think was thought all the way through involves shaking a soda can as fast as you can in order to make your can spray further than your opponents' cans. How do you make your character shake the can? By shaking the Wiimote up and down, of course!
Go get a Wiimote, shake it up and down, and you tell me what that looks like. I'll wait.
Made even worse when the objective involves spraying...
I was playing the game with three other people when that minigame popped up. Don't know whose presence made it more awkward; my mother, my boyfriend, or my nine-year-old brother. XD
